Definitions

  • the present invention concerns an aerial-stabilizer rudder for vehicles.
  • centrifugal force is, as is well known, independent of the mode of propulsion utilized for the vehicle, or the manner in which the propulsive forces are utilized to move the vehicle.
  • vehicles operated by combustion, steam, electrical, aerial propulsion, or turboiet engines and that run on wheels, on the roadway, on tracks, on air cushions, or are operated by other propulsion means or run on other surfaces or other means are subject to centrifugal forces.
  • centrifugal force can be described as the tendency of the object to continue in a straight line when forces tending to change its direction act upon it.
  • centrifugal forces must be carried and counteracted by the wheels, suspension, transmission, or other analogous means, depending on the vehicle, and therefore act to reduce the useful life of these devices.
  • skidding and overturning of a vehicle often places the life of its operator and passengers in jeopardy, as well as the life or health of persons nearby.
  • the performance of the vehicle suffers as the operator of the vehicle must reduce the speed of the vehicle while taking a corner in order to maintain control of the vehicle, and thereafter must re-accelerate to regain his previous speed. This last problem is especially important to racecar operators during a race.
  • the aim of the invention is to reduce to a minimum, and as far as possible, even eliminate, all the above mentioned disadvantages, by teaching means that, when conveniently mounted on said vehicles, are able to maintain the same in equilibrium while taking a corner, utilizing air pressure to oppose or counteract the centrifugal force generated by the vehicle.
  • These means are composed of an aerial-stabilizer rudder which is to be secured to a vehicle and which utilizes air pressure generated by the apparent wind acting on it to restrain the tendency of the vehicle to side skid and possible overturn because of centrifugal forces generated when the vehicle executes a high speed turn.
  • This aerial-stabilizer rudder can be of any elongated shape, such as in form of an arrow, a rectangle, a rhomboid, a square, round, in the form of a banana. It is to be mounted on the top of a vehicle. It is important that the rudder is fixed to a vertical support, in the centre of the surface of the rudder himself. The vertical support must be placed in the exact centre of gravity of the vehicle. The aerial-stabilizer rudder will be therefore fixed in the direction of travel of the vehicle.
  • FIG. 1 is a schematic view of a car, with the aerial-stabilizer rudder fixed on it;
  • FIG. 2 is a schematic view of another embodiment of the aerial-stabilizer rudder, with more weight concentrated on the back part of the rudder;
  • FIG. 3 is a schematic view of an embodiment that provides the application of two aerial-stabilizer rudders.
  • FIG. 4 is a schematic view of an embodiment of the aerial-stabilizer rudder showing an additional weight mounted thereto;
  • FIG. 5 is a schematic view of a car, with the aerial-stabilizer rudder fixed on it, showing a transmission linking the steering mechanism of the car to the rudder.
  • the directional control of the so-placed aerial-stabilizer rudder 1 may be by means of the steering of the car 3 controlled, in a proportioned and simultaneous manner related to the steering, by means of convenient transmissions, electrical or hydraulical devices, or other well known means.
  • the rudder, controlled this way, will be operable to rotate to the left, when the car is steered to the left, and to the right, when the car is steered to the right.
  • the aerial-stabilizer rudder will have air pressure pressing against its right face to counteract the centrifugal force.
  • the force of a pressure on the aerial-stabilizer rudder therefore will be opposed to the centifugal forces generated by the vehicle as it executes a turn.
  • the net skidding force will, as a result, be reduced by a very high percentage, and, consequently the tendency to side-skid and overturn will also be reduced.
  • the object of the present invention can be also realized in a different embodiment of the invention.
  • the aerial-stabilizer rudder 1 is free of control by the steering mechanism of the car.
  • Control of the rudder 1 is accomplished by weighting the rear portion thereof so that the rudder will displace itself automatically by centrifugal forces generated when the vehicle executes a turn.
  • the rudder 1 is secured to the vertical support 2 along a portion of the rudder which is slightly anterior to the central portion of the surface of the rudder. This will place a greater weight of the rudder on the rearward portion thereof and the rudder will act as if it has had additional weight secured to the rearward portion thereof.
  • the heavier rearward portion of the Aerial-Stablizer Rudder will be rotated outwardly with respect to the direction of change of the vehicle. This way, it will act as if it were directly controlled by the steering.
  • two (or more) rudders 1a and 1b can be fixed to the same car.
  • the dimensions of the aerial-stabilizer rudder are to be related to the weight, the kind and the speed of the car.
  • the normally rearward portion 4 of the rudder 1 may have a weight 5 mounted thereto using a bolt 6 or other convenient means, as shown in FIG. 4.
  • a transmission 8 may be provided between the steering system 7 and rudder 1 as schematically shown in FIG. 5.
